Heart failure while running. This silent threat can be prevented by going for a heart checkup before running.

Exercise is something healthy you should do. Regardless of whether you are a new or beginner runner or a pro who is looking to up your level of running or exercise to be more intense, going for a health check-up before your exercise and run (cardiovascular pre-participation screening) is important to determine risk of heart disease and prevent sudden death during exercise.

• People whose doctors diagnosed coronary artery disease or myocardial infarction before. 
• People whose doctors diagnosed a myocardial or pericardium disease or congenital heart disease or heart failure or cardiovascular disease along with cardiac ischemia, severe arrhythmia or abnormal heart function.
• People who have symptoms that match with cardiovascular disease such as chest tightness; chest pain; jaw pain; fatigue; breathing difficulty while sitting, lying down, exercising, lifting heavy objects, angry or excited; breathing difficulty at night that causes them to wake and sit up to breathe; heart palpitations; dizziness; and fainting or loss of consciousness, especially during exercise or when getting up to change posture.
• People with risk factors for cardiovascular disease such as direct family history (of males younger than 55 years or women younger than 65 years)  who become sick or die due to cardiovascular disease or smoking behaviors, diabetes, hypertension, high cholesterol or cardiac arrhythmia.
• People who suspect or are unsure whether or not they belong to the risk group.
